Abstract (en)

[origin: EP0924041A1] For more efficient transporting of the concentrated granulate and cooling fluid to the dryer(14) the dispersion is transported in a conveying pipe(13) with greater length, but smaller diameter than the first pipeline(5). Preferred Features: The dispersion is pumped either before or after separation of part of the fluid and can be conditioned either prior to transporting to the dryer(14) or just before entering the dryer. The separated part of the fluid can be varied as an adjustable variable using either: a) the granulate content of the dispersion and/or b) the dispersion flow rate and/or c) the dispersion pressure as a control variable. Separated water is recirculated.
